| Connections | 1/4″ tube fittings |
| Others | Overflow cylinder, sample chamber (200 ml), ball valve |
Typical Installation Mode
1 – Preparation
Place a new septum on the sample bottle. Insert the bottle with cap and septum into the sleeve until the septum is pierced by the needles. Swing down the bottle retaining clip.
2 – Vacuum
Turn the handle on the top of the overflow cylinder to the “VACUUM” position to vacuumize the overflow cylinder. Turn the handle to the “OFF” position.
3 – System Purge
Turn the main handle to the “PURGE” position, allowing the sample to flow the process line into the vacuumized overflow cylinder through the sample chamber to ensure representative sampling.
4 – Sampling
Turn the main handle to the “SAMPLE” position, allowing nitrogen to force the sample from the sample chamber into the bottle and purge the sample chamber and needle assembly. The amount of sample depends on the sample chamber volume.
5 – Back Purge
Turn the main handle on the top of the overflow cylinder to the “PURE” position, allowing nitrogen to force the residual sample from the system into the process line.
6 – Off
Turn the two handles to the “OFF” position to close the sampling system. Remove the bottle retaining clip and take out the bottle from the sleeve. The septum reseals automatically to complete the sampling process.
